Abstract (en)

[origin: US4629341A] For underlining a text section a command is typed both before and after the text section in the typing sequence, which command causes the storing of position values in two registers. The underlining is then performed underneath the already entered characters. A command for line advance, facultatively in connection with returning the printing head to a left position, ensures that the underlining will be performed prior to the line advance, but that the conditions for the underline will be retained also for the next line.
